Wanted to thank you for all the help on the phone the other day with the “power valve flutter” I was experiencing in the mid range under load (primarily in the snow). Adjusted power valve to about a millimeter from flush, slightly less than it was stock completely solved the issue. TE300i, medium comp head, air screw .5 turns, idle screw installed after a couple rides. The bike is running fantastic, most dialed in 300 motor I’ve ever ridden. Super pumped for the upcoming race season. You should have a few eager customers heading your way soon.
